I've written an Android program with 4 levels of user: Engineer, Recipie Manager, Operator and Viewer, in order to operate a Bioreactor.I was growing some control code for a Maximite (australian microcontroller), but realised I needed more power,so bought an Arduino Due (ARM).The status was: GUI basically works.I have played with a $3 bluetooth to serial converter for the maximite, and Atlas scientific pH and DO sensors, and bought an arduino motor controller for impeller and relay board for the valves/feed motors for O2, media, etc.I was thinking of putting this on sourceforge.net as a project - I can do GPL if that's what people want, and then looking for collaborators.Status is currently GUI works. Charting to do (interface defined). Bluetooth to do. Microcontroller code to do (have a demo of this - it's pretty easy really).Idea is to store run data on a SD card near the microcontroller.Anyone interested in collaborating on this project, or know of people working on an equivalent?Jeff Daviesjeff.davies (at) gammasensors.net
You mean like this?

I am very interested in discussing what sensors you have evaluated for use in your project. The Atlas boards look good from their site but those are just the signal conditioners not the sensors themselves (I would assume they are simply repackaging the sensors of other OEM brands). Also I dug quite a bit into semiconductor pH sensors (instead of glass), that is the real way to go.
Maximite is definitely a strong enough controller board to handle the job, though obviously you don't want to write it in BASIC, if you're doing that then it won't work, that is the real limitation there. You would run into the same problem with Arduino as well. The maximite uses a 32-bit MIPS-core chip which is actually better than the ARM, just don't expect to be able to write BASIC code (intended for kids) and have it work. It's like the difference between writing a web page with javascript compared to writing an iPhone App.
It also seems like you are a commercial company, so, that might bias some collaborators.
